67 year old male, retired. Since getting my Garmin Vivoactive 5 I've been watching the Sleep score and Body battery when waking up in the morning. I think it's pretty spot on for me. I sleep really well after a day of SBR training. Specially master swim days where I probably due the most intensity compared to moderate days of biking and easy running.

I still love coffee in retirement and I drink about a pot a day, finishing the last cup (microwaved) at dinner. I rarely drink alcohol any longer and if I do I find that those little airplane bottles of Fireball don't keep me up peeing all night ;) I take regular hour naps during the day.

Funny, when I was working I'd tell myself I'll never get up early again but I still find myself getting up around 4am on master swim days and I can't sleep past sunrise (shines through the bedroom window). In full disclosure I go to bed really early, like 8pm on swim nights and around 9pm any other night.

And on CBD/THC, I tried the 5mg gummies at night. At first, I thought they worked really well but after a while I figured out my sleep was more restful without taking them. YMMV
